尽管一些饮食障碍预防计划减少了女高中生和大学生的饮食障碍风险因素和症状，但针对女中学生的有效预防计划很少，尽管那时经常会出现身体形象和饮食障碍。两项试点试验评估了一项新的基于不和谐的饮食障碍预防计划，该计划针对有身体形象问题的中学女孩。来自两个地点(研究1：81人，男性12.1岁，SD=0.9；研究2：52人，男性12.5岁，SD=0.8)的女中学生被随机分为不和谐干预组(MS Body Project)和教育手册对照组；研究2包括3个月的随访。研究1和研究2的6个变量中只有一个变量在测试后显著减少(即分别是瘦身压力和消极情绪)，尽管测试后效应大小表明进食障碍的风险因素和症状有中等程度的减少(研究1的MD=0.40；研究2的MD=0.65)；研究2的3个月随访时的减少并不明显(MD=0.19)。结果表明，这个新的中学版的身体项目在后测中对饮食失调的风险因素产生了中等幅度的减少，但效果显示出有限的持久性。继续改进和评估这一干预措施似乎有必要为这一年龄段制定更有效的预防计划。
Although several eating disorder prevention programs reduce eating disorder risk factors and symptoms for female high school and college students, few efficacious prevention programs exist for female middle school students, despite the fact that body image and eating disturbances often emerge then. Two pilot trials evaluated a new dissonance-based eating disorder prevention program for middle school girls with body image concerns. Female middle school students with body dissatisfaction from two sites (Study 1: N = 81, M age = 12.1, SD = 0.9; Study 2: N = 52, M age = 12.5, SD = 0.8) were randomized to a dissonance intervention (MS Body Project) or educational brochure control; Study 2 included a 3-month follow-up. Intervention participants showed significant posttest reductions in only one of six variables with both Studies 1 and 2 (i.e., pressure to be thin and negative affect, respectively), though posttest effect sizes suggested medium reductions in eating disorder risk factors and symptoms (Study 1 M d = 0.40; Study 2 M d = 0.65); reductions at 3-month follow-up in Study 2 were not evident (M d = 0.19). Results suggest that this new middle school version of the Body Project is producing medium magnitude reductions in eating disorder risk factors at posttest but that effects are showing limited persistence. Continued refinement and evaluation of this intervention appears warranted to develop more effective prevention programs for this age group.
